IMPROVEMENT IN BOX-MACHINES.

Specification forming part of Letters Patent No. 163,237.; dated May 11,1875; application filed March 1, 1875.

To all whom 225 may concern:

Be it known that we, SAM. K. PAIGE, GEORGE W. PAIGE, and JEREMIAH A.PAIGE, of Henniker, in the county of Merrimack, State of New Hampshire,have invented a certain new and useful Improvement in Box- Machines, ofwhich the following is a description sufficiently full, clear, and exactto enable any person skilled in the art or science to which ourinvention appertains to make and use the same, reference being had tothe accompanying drawing forming a part of this specification, in which-Figure 1 is an isometrical perspective view 5 and Fig. 2 a sectionalside elevation, showing the construction of the drum or cylinder.

Like letters of reference indicate corresponding parts in the differentfigures of the drawmg.

Our invention relates to that class of boxmachines which are designedfor manufacturing round or cylindrical boxes, and consists in a novelconstruction and arrangement of the parts, as hereinafter more fully setforth and claimed, by which a simpler, cheaper, and more efiectivedevice of this character is produced, than is now in ordinary use.

In the drawing, A represents the body or frame-work of the machine,which is provided with the uprights b I), having the cross-head O, towhich is framed the vertical bar as. J ournaled at n in the uprightsthere is a horizontal shaft, 2, provided at one end with the wheel R,and carrying at its other the drum or cylinder Q. This drum is composedof two annular heads, 3 and a body of hard elastic sheet metal,preferably rolled brass, and is evolute in form, having longitudinalshoulders m, at which point the distance from the periphery to its axisor the shaftz is greatest, and from which point around the drum, in thedirection of the arrow, the diameter gradually decreases to the base ofthe shoulder, where it is least. The sheet-metal covering projectsslightly over the shoulder, forming a lip, as shown at r, and from theshoulder around the drum, in the direction of the arrow, to a pointnearly opposite the shoulder,

, it is firmly attached to the heads y, leaving the end a free. Theupright b above the cylinder Q, and the bar 00, are provided withgrooves E on their contiguous sides, forming ways or runlets for thevertically-arranged sliding stock D. This stock is provided with tworods, ff, fitted to work in holes through the cross-head G, and aroundthese rods are arranged spiral springs g g, which act expansivelyagainst the head, and set-screws h h, to keep the stock D from contactwith the drum Q when the machine is not in operation. A presser-bar, 1,is attached to the lower side of the stock, being curved on its underface to correspond with the curvature of the drum,

and to the outer edge of the bar there are fitted two frictionguide-rollers, 10 p. lPivoted at one end to the bar as there is ahorizontal lever, L. This lever is also jointed at K to the arm Jconnected with the stock D, and at M to the rod N connected with thetreadle O. J our naled longitudinally in the heads 3 at one side of theshaft 2, and immediately under the free end a, of the metallic coveringof the drum, there is a shaft (not shown) having at its outer end thecrank T, and supporting the interiorly-arranged cam or eccentric o. Thiscam is so disposed on the shaft that when the crank T is turned it willbe brought against the inner surface of the end a, forcing it outwardlyagainst the lip 0, under which it extends, a spring-catch, U, beingattached to the heady, for retaining the shaft in position when soturned.

In the use of our-improved machine the veneer or blank from which thebody of the box is to be formed has one of its edges or ends insertedbeneath the lip 'r and against the shoulder m. The crank T is thenturned to move the cam 12 against the inner side of the end a, forcingit outwardly and firmly grasping the blank between the end cand lip r,the crank being secured by the spring-catch U. The presser-bar I is thendepressed and kept in forcible contact with the blank or veneer by meansof the treadle 0, the wheel R at the same time being turned to revolvethe drum in the direction of the arrow. As the drum revolves, the blankwill be wound or wrapped closely and smoothly around the same, beingfirmly held down by the presser-bar until its free end is nearlyreached, when the machine is stopped and the ends of the blank joined bymeans of nails or tacks driven through the same against the metalliccovcringof the drum by which they will be headed or clinched. After thebox is properly nailed, the crank T is turned back, disconnecting thecam '0 from the end a, which immediately contracts or springs inwardly,reducing the diameter of the drum, and freeing the box so that it may beremoved in a manner which will be readily understood by all conversantwith such matters without a more explicit description.

It will be obvious that the machine maybe 7 adapted to the manufactureof boxes of any required size by merely ohan gin g the drum andpresser-bar.

Having thus explained our invention, What we claim is In a box-machine,substantially such asdescribed, the presser-bar I combined to operatewith the drum Q, substantially as and for the purpose set forth.
